I haven't made a change to the spec here. I do believe, however, that it would be perfectly reasonable for a user agent to offer the user the choice to stop supporting JavaScript from any modal prompt. Other possible ways of handling this are to make the alerts tab-modal only, and to still allow navigation using the UI (location bar) while one of these "modal" dialogs is up, and simply aborting all running scripts when that is done. Basically, I think this is a UA UI issue, and out of scope for the spec. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
